Lovato recently posed for the June/July 2016 issue of Latina where she discussed about her new music. She stated: “I don’t care about radio hits. When you try hard for that, it doesn’t happen. It’s songs like ‘Stone Cold’ that I don’t get tired of singing on tour. I get tired of singing ‘Give Your Heart a Break’ and even ‘Confident’ already. I have yet to reach my peak, and also, my voice is better now than it was a year ago. Now I can show people what I can do. There’s a lot of pain that I experienced over the past year, and I’m so ready to write about it. I’ve stayed sober through it all, I’m a stronger person, but it’s definitely been a very painful year,” She explained that her next album “will have a more soulful vibe.” 
- "Sorry Not Sorry" was announced as the lead single from the album on July 6, 2017. . It is set to be released on July 11, 2017.
